Slate Roofing

The Durable Slate Company is equipped for every slate roof on any kind of building. Residential, commercial, or place of worship, new roof or a century standing. With us, your slate roof will truly stand the test of time and look beautiful for ages to come.

With one of the largest stocks of reclaimed slate in the country, we can match most slate roofs whether performing a complete restoration, or installing a slate roof on an addition, or repairing large sections damaged by fire, wind, storms, and other forces of nature.

Clay-Tile Roofing

We install, repair and restore all types of clay roof tiles expertly, by contractors with in-depth knowledge and respect for the roofing material.

The repair and restoration of old clay tile roofs should only be done by a roofing contractor with suitable expertise; too often tile restoration is carried out by contractors without the in-depth knowledge and skill required, resulting in many ruined clay tile roofs. Choose Durable instead.

Copper Roofing

The Durable Slate Company installs all types of copper roofing including standing seam, batten seam, soldered flat lock, copper shingles, diamond pattern, and other custom systems.

With proper fastening, skilled handling of joints, and adequate consideration for thermal and building movement, a well-installed copper roof can last many decades with little or no maintenance.

Copper Gutters

We install all types of hanging copper gutters from standard 16oz. k-style to custom heavy gauge gutters with bar stock supports to withstand the harshest winters. We can replicate all ornamental gutters, collector heads, and downspouts.

Leaks in these gutter systems can cause extensive interior damage, and, if not properly repaired, may result in structural damage.
